In this day and age it’s not uncommon for a mobile application to take the world by storm; Angry Birds being a prime example. Originally launched by Rovio for platforms like iOS and Android back in 2009, Angry Birds features the very simple premise of catapulting an arsenal of ability equipped birds at legions of maniacal pigs. Despite this simple premise Angry Birds has consistently topped the respective mobile app store charts, grossing Rovio and associated companies millions upon millions of dollars.

But mobile gaming isn’t the only category with highly popular applications, as Instagram has seen similar success. This application, as we’re sure to all know by now, allows iPhone (along with iPad & iPod touch) users to snap a picture, apply a filter, and then share it with friends through social networks like Twitter, Facebook and more. While it’s currently only available for iOS, which powers the aforementioned devices, that hasn’t stopped the application from accumulating more than 150 million uploads.

iOS is unquestionably popular in its own right, but with so many different devices hitting the market running Google’s Android, a native Instagram client has been highly sought after. Luckily, the developers behind the popular app have said many different times that they will in fact be bringing Instagram to Android at some time in the near future. Unfortunately, at this point, it’s anyone’s guess as to when exactly it will drop.

Last we heard of the Android version of Instagram was at SXSW, where it was briefly displayed and said to be coming soon. Now, the developers behind Instagram have launched a sign up page for the Android version. Upon visiting the page you will be able to input your email address for notification of when the Android application drops. Of course, this doesn’t technically mean that it will be launched soon, but it will definitely elicit a sigh of relief to know that the app is definitely on its way.
